Regarding the newly established order; I simply mean "if it establishes a mini-capitalist market within Socialism".

define mini capitalist market

I mean it is a market technically if we are trading things

so certain things will be rare and will be worth more than other things at a given time

Well, yes. Earnestly? It'll probably be something that men and people smarter than me will have to respond to.. But...

Its a frisky matter.

A black market? No.

Well maybe we ought to work out these minor details b4 the violent revolution

Do you get what I mean? Kind of?

*That makes sense.*

So I know whether trading oranges will lead to my execution

No.

I would say that, in general, peer-to-peer trading wouldn't be an issue.

It would only become such if the structure of capitalism is being gradually re-built.

With the threat of force to back it up, especially.

(Even if those people use a personal currency.)

Here's the thing: I get 10 of my neighbors together, each of us has a home with a lawn, and each of us has converted part of his lawn into a garden where he plants things. No hiring of workers is going on here, it's personal property. I plant my seeds, water them, etc. Now, I specialize in growing carrots, Bob specializes in cabbage, etc. Because it's inconvenient for us to always trade veggies we use Snakebucks as a handy IOU to help simplify this process.

That is fine.

Can I loan Snakebucks?

Yes.

Can I collect interest?

Assuming it is not forceful and consensual, yes.

Well when Bob asks me if he can borrow some Snakebucks we sit down and hash out the terms of the loan, and he agrees to give something up if he fails to pay on time.

If the time comes and he can't pay, surely what he promised to give me is now my personal property, yes?

For good measure, let's say the whole arrangement has been put into writing, signed by both of us, and witnessed/signed by a third party

It sounds fair to me, even though I feel kind of suspicious of the whole contract and how that could be expanded to exploit Mr. Bob. But, if Bob agrees and is of sound mind. Then it would be valid.

Some form of contract would have to exist for Craftsmen Unions and Co-Operatives to function smoothly, anyway.

Okay, one more question: let's imagine Bob knows if I lend him Snakebucks in all likelihood he won't be able to pay them off when the time comes, so he doesn't want to borrow them, but he really wants some Snakebucks. He has an offer for me: he will help me plant my carrots, and in exchange for his assistance, I'll give him Snakebucks.
Is that okay?

That is going a bit too far in just re-constructing the capitalist market.

lol you were fine with it a sec ago

I don't see the big problem here

In that first place, it all seems unneeded and complicating things that are simple.

just a couple bros trading personal prop

But-

a couple good ol socialist comrades 😉

If that is just what they want.

I guess... Whatever.

So what I've described is ok under socialism?

If the mode of production is firmly socialistic in wider society.

We're not breaking any rules here

It would be unreasonable to police it and it also wouldn't develop.
